2 Claims.

This invention relates, generally, to the packaging of coins in wrappers; and the invention has reference, more particularly, to a novel crimping machine or cluster crimper having a plurality of crimping devices adapted for crimp-v ing the ends of the wrappers for various denominations of coins or the like.

Crimping devices as heretofore generally constructed, are each capable of crimping the wrappers of but a single denomination of coin, so that it is necessary to employ a plurality'of these Inachines or devices when it is desired to crimp the wrappers of coins of several denominations.

Theprincipal object of the present invention v is to provide a novel crimping machine or cluster crimper having a plurality of crimping devices or crimpers which are arranged adjacent one another and are simultaneously operated, said cluster crimper being designed to crimp coin wrappers of various sizes corresponding to any desired combination of coin denominations.

Another object of the present invention lies in the provision of a novel cluster crimper for coin wrappers wherein the crimpers of various denominations are disposed circumferentially with respect to-one another and have their operative ends facing in a single direction and lying in a common plane, thereby rendering each of these crimpers readily accessible for crimping the ends of coin wrappers.

Still another object of the present invention is to provide a novel cluster crimper of the above character wherein the several crimpers for wrappers of variousdenominations of coins are driven from a single motive means through the use of suitable gearing.

A further object of this invention is to provide individual crimpers of self-cleaning or non-clogging construction, the same having discharging passages rearward of the centering plugs and crimper studs through which particles of paper, fibers, dust, etc., accumulating during the crimping operations, may escape. so that clogging of the interior of the crimpers is eliminated; and the invention has for a still further object to provide individual crimpers with means for engaging coins within the wrappers, to thereby hold the coins and their wrappers in proper alignment with the crimping studs during the crimping operation, whereby a tight and neat crimped wrapper is produced.

Still another object of the present invention is to provide a novel. cluster crimper of simple, rugged construction which is adapted to be readily mounted on a suitable support, the same being adjustable with respect to said support to enhance the ease of application of coin wrappers to the crimpers of the device.

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same. i

The invention is clearly illustrated in the accompanying drawings, in which:

Fig. l is a view in front elevation of the novel cluster crimper of this invention, the said cluster crimper being illustrated as mounted upon a table.

Fig. 2 is a view in side elevation of the structure shown in Fig. l. 79

Fig. 3 is an enlarged sectional view taken substantially along line 3-3 of Fig. 2 looking in the direction of the arrows.

Fig. 4 is a fragmentary View of a portion of the structure of Fig. 3 and illustrates the manner of applying a coin wrapper to a crimper; and

Fig. 5 is a view looking at the crimper cover from the rear.

- Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now to said drawings, the reference numeral 1 designates the novel crimping machine or cluster crimper of this invention as a whole. Cluster crimper 1 is illustrated as mounted upon a table 2 and comprisesa driving motor 3which is illustrated as of the electric type. Motor 3 is adapted to be supplied with electric current by means of a cable 4 and plug 5 which may be plugged into a convenience outlet fi'supplying, for example, 110 volt a. 0. Motor 3 has its base '7 secured as by screws 8 to an angle shaped bracket member 9. Bracket member 9 is formed at the side thereof opposite to the motor 3 with a circular boss 11. A threaded stud i2 is anchored centrally in the boss 11 and extends outwardly therefrom. Stud 12 projects through a suitable aperture provided in the upper end portion 13 of a clamp l i. Upper end portion 13 of the clamp 14 is shaped to conform to the circular boss 11, as especially shown in Figs. 1' and 3. A wing nut 15 is threaded upon stud 12 and by engaging upper end portion 13 of clamp 14 is adapted to secure thebracket member 9 to the clamp 14. By loosening wing nut 15, th bracket member 9 may 105 be adjusted angularly somewhat with respect to the clamp 14, whereupon the tightening of wing nut 15 will lock the bracket member 9 in adjusted position. H

Clamp 14 is provided with a hand screw 16 a bearing aperture provided in the forward portion 18 ofthe gearcasing.

which is threaded through the lower portion of this clamp and is adapted to engage the top of table 2, to thereby secure clamp 14 firmly to this table. A substantially cylindrical. gear casing is secured to the forward portion of bracket memher 9. This gear casing comprises a rear portion 1'? and a forward portion 18 which are'secured together by circurnferentially spaced screws 19. The rear portion 1'? of the gear casing is secured to the forward portion of bracket 9, as by screws 21. This rear portion 17 of the gear casing is provided with a central axial bearing aperture 22 for receiving a rotatable shaft 23 that is adapted to be driven by the armature shaft 24 of the motor 3. Shaft 3 is provided with an axial bore for receiving the outer end portion of arn ature shaft 2%. The end of shaft 23 facing the motor 3 is slotted at 25 for receiving a pin 26 carried by the armature shaft 24. Pin 26 by engaging the wall of slot 25 serves .to drive shaft 23 from the armature shaft 24. Shaft 23 is formed with a reduced extension 27 which extends forwardly and has its free end portion mounted in A driving pininon 28 fixed upon the reduced extension 27 of shaft 23 within the gearing cas ing 17-48. Driving pinion 28 meshes with a plurality of gears 29 which are disposed circumferentially around the driving pinion 28 and contained within gear casing l7-l8. Five such gears 29 are shown in the form of the invention illustrated in the drawings, but it is to understood that a greater or lesser number of these gears may be used depending upon the number of crimpers possessed by the clust r crimper. Gears 29 are fixed upon cylindrical shanks 3 which are iormed as rear extensions of substantially cup shaped crimper bodies 31, 32, 33, 34 and 35, respectively. Shanks 30 are rotatably mounted in bearings provided inthe front and rear walls of casing l7l8.

Criznper bodie are of varying diameters so as to conform to the several denominations of coin wrappers adapted to be operated upon by the machine. These sub stantially cup shaped. rimper bodies have hol-- low interior coin wrapper receiving recesses 36. The forwarc edge portions of the crimper bodies are beveled at 38 adjacent the receiving recesses 36 to facilitate the insertion of coin wrappers into these receiving recesses. The rear portions of the crimper bodies 31 to 35 have their opposite sides cut away as indicated at 37 to thus provide discharge passagesBl' leading out of the hollow interior recesses 36. Centering plugs 39 are positioned centrally within the wrapper receiving recesses 36. These centering plugs are of cylindrical shape and are each of lesser diameter than the respective wrapper receiving recess 36, withinwhich'the same is positioned; The annular space, thus provided between a plug 39 and the-interior wall of the wrapper receiving recess 36, is adapted to receive the cylindrical open ends of coin wrappers. These centering plugs have rearward extensions i1 projecting snugly into suitable recesses provided in the bottoms of the crimper bodies. Each of th centering plugs 39 is formed with an annular, marginal, forwardly projecting centering rib 40.

A pair of crimper studs 42 extend between each of the centering plugs 39 and its respective crimper body; These crimper studs 42 project radially outwardly from the centering plu at opposite sides of this plu The inner end portions of front wall of crimpe 31 to 35 are of similar shape but the crimper studs extend into pockets provided in the centering plug, whereas the outer end portions of these crimper studs extend through radial apertures provided in the crimper bodies. Set screws' l are threaded into the crimper bodies and engage the outer portions of crimper studs 42 to retain these studs in fixed position with respect to the crimper bodies and the plugs 39. The exposed portions of the crimper studs 42 which lie in the annular space intermediate the centering plugs and the crimper bodies are formed with substantially semi-circular grooves 45, which grooves extend completely around the crimper studs 42. The outer end portions of the crimper studs are illustrated'as provided with slots l6 as for receiving a screw driver. Each of the crimpers, comprising a crimper body, a centering plug and a pair of crimper studs 42, is adapted to be rotated by one of the gears 29.

A cover or guard 4.7 of substantially cup-shape overlies the front portion of gear casing l'7l8 and surrounds the crimpers. Cover or guard 47 is formed with external longitudinally extending ribs lawhich have rear extensions overlying the "1g portion 18, which rib extensions are socui dto this casing portion as by screws 49. The front wall of cover 47 is provided with apertures so to 54 for receiving the forward end portions of the crimper bodies. It will be noted that apertures 50 and 51 surrounding the larger bodies to one another. The forward surface of front wall is substantially flush with the forward ends of the crimper bodies. Front wall is suitably reinforced by ribbing 59 at the rear thereof. Five spaced lugs 56 extend radially outwardl wall 55. These lugs are marked with embossed numbers, which numbers are l, 5, 25, 50 and 10, designating corresponding coin denominations. The cover or guard 47, in addition toits function of guardin the rotated crimper bodies against contact by the fingers of the operator when using the machine, also serves as a' collection chamber" to receive and collect lintand other foreign matter discharged from the rearward escape openings of the crimper bodies.

In use, with the clamp 14 mounted on table 2, the nut 15 is loosened and the bracket-member 9 adjusted so as to dispose the several crimpers conveniently to the machine operator, whereupon the nut 15 is again tightened. Upon inserting plug 5 into outlet 5 the armature shaft 24 of motor 3 drives shaft 23 and pinion 28, which pinion in turn drives the gears 29 disposed therearound. These gears in turn revolve the shanks 30 of the crimper bodies, thereby revolving the several crimpers disposedcircumferentially with respect to one another at the front of the machine. Assuming it is desired to crimp the ends of a coin wrapper 57 (see Fig. 4) which coin wrapper is filled with fifty cent pieces, the coin wrapper 5'7 together with the coins therein is then manipulated so that the end of the wrap{ per enters the wrapper receiving recess36 of the fifty cent crimper, which crimper is" so designated at the forward part of the machine by the'number 50 marked on the front wall of cover 47. As the end of Wrapper 57 enters the wrapper receiving recess 36, this wrapper end will be engaged by the rapidly revolving grooved portions 45 of thecrirnper studs 42, which grooved portions act to rapidly and neatly crimp the end edge of the wrapper over in the manner indicated in Fig. 4. During thiscrimping operation,

31 and 32 are of such size as to from the peripheral edge portion of front the end coin 58 abuts the centering rib 40 of the centering plug 39, and this annular centering rib acts in conjunction with the wall of the receiving recess 36 to properly center the coins and the wrapper so that they are held in proper alignment with the crimper during the crimping operation. This aligning action of the plug 39 and crimper body 31 causes the crimp formed on the end of the wrapper to be positioned in a plane which is truly transverse of the wrapper length. The cluster crimper illustrated in the drawings is adapted to readily crimp the ends of wrappers holding any denomination of coin from one cent to fifty cents by merely inserting these wrappers into the proper crimper.

The action of the rapidly revolving crimper studs 42 is positive and quick so that the desired crimping edge is almost immediately formed upon the wrapper, which crimping edge serves to retain the coins positively within the wrapper and prevents their dropping therefrom when the wrappers are handled and also prevents the unraveling of the wrapper should the wrapper be of the fiat type. In the event thatthe portion of the groove 45 of the crimper stud which engages the ends of the wrappers should become worn, the stud may be loosened by loosening the proper set screw 44 and the crimper stud turned slightly, as by means of a screw driver, so as to present a new groove portion to the ends of the wrappers.

During the use of the individual crimpers, the rotation of the crimping studs 42 against the end of an inserted wrapper, while curling or crimping such end, tends to slough off paper fibers and particles, dust, etc., which is constantly pressed back into the recesses 36. In time such accumulations so fill the recesses as to tend to obstruct proper operation of the crimper studs, making it necessary to more or less frequently stop the machine, and laboriously dig out the accumulated matter so as to again clear the crimper for proper functioning. Such difhculties are eliminated in the novel form of crimpers provided by this invention, since the accumulations mentioned readily discharge themselves out of the recesses 36 through the discharge openings 37', which thus assures a more erficient operation of the crimpers, and avoids necessity for more or less frequently stopping the machine to clear out the recesses of said crimpers,

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof,

it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
